#405 ‒ AMA #88: Metabolic liver health: how to assess risk, catch dysfunction early, and prevent or reverse liver disease

Hey, everyone. Welcome to a sneak peek ask me anything or AMA episode of the drive podcast. I'm your host, Peter Attia. At the end of this short episode, I'll explain how you can access the AMA episodes in full along with a ton of other membership benefits we've created. Or you can learn more now by going to peteratiamd.com forward slash subscribe. Without further delay, here's today's sneak peek of the Ask Me Anything episode. Welcome to Ask Me Anything AMA episode 88. Today, we are talking about the liver, and specifically its role in metabolic health. This is a topic that suffers from a strange mismatch. On the one hand, the liver is one of the most metabolically important organs in the body. It is the mastermind sitting at the center of how we handle glucose, fat, and cholesterol. On the other, most of the public conversation about the liver is about detoxes, cleanses, and supplements, while the questions that actually matter go unasked. We're going to focus on one of the liver's main functions, how it serves as the centerpiece of the whole body metabolism, and walk through how to tell whether yours is under stress, why that matters, and what actually moves the needle once you need to act. Specifically, we're going to cover why the liver is the so called canary in the coal mine for metabolic dysfunction, the four stages of progression from metabolic stress to fibrosis, and which stages are reversible, why normal liver enzymes can be misleading and what we actually use to detect end stage risk, what interventions work once risk or disease is identified, plus an honest look at whether any liver supplements are worth taking.

Pretty good. Thanks. Awesome. So today, we are doing the whole episode around one topic, which is the liver and metabolic health. In the past, you've described the liver as the quote, unquote canary in the coal mine for metabolic dysfunction. So I think it'd be helpful to start with kind of talking about what you mean by that and why you think the liver is so important. Well, the liver sits sort of at the center of systemic metabolism for every macronutrient, glucose, fat, protein, as well as cholesterol. By the way, let's not forget ethanol or alcohol there as well. It's also one of the very first places to both promote and respond to stress from anywhere in the system. If circulating triglycerides are high, the liver gets involved. If glucose regulation is deteriorating, the liver's involved. If ApoB or LDL cholesterol is climbing, the liver made those particles. The flip side is …
